DETAILED DESCRIPTION

Example configurations will now be described more fully with reference to the accompanying drawings. Example configurations are provided so that this disclosure will be thorough, and will fully convey the scope of the disclosure to those of ordinary skill in the art. Specific details are set forth such as examples of specific components, devices, and methods, to provide a thorough understanding of configurations of the present disclosure. It will be apparent to those of ordinary skill in the art that specific details need not be employed, that example configurations may be embodied in many different forms, and that the specific details and the example configurations should not be construed to limit the scope of the disclosure.

The terminology used herein is for the purpose of describing particular exemplary configurations only and is not intended to be limiting. As used herein, the singular articles “a,” “an,” and “the” may be intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms “comprises,” “comprising,” “including,” and “having,” are inclusive and therefore specify the presence of features, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and/or groups thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring their performance in the particular order discussed or illustrated, unless specifically identified as an order of performance. Additional or alternative steps may be employed.

When an element or layer is referred to as being “on,” “engaged to,” “connected to,” “attached to,” or “coupled to” another element or layer, it may be directly on, engaged, connected, attached, or coupled to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly engaged to,” “directly connected to,” “directly attached to,” or “directly coupled to” another element or layer, there may be no intervening elements or layers present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.

The terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections. These elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as “first,” “second,” and other numerical terms do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example configurations.

Referring to FIGS. 1A and 1, a fluid retainer cartridge assembly is shown generally at 10. The fluid retainer cartridge assembly 10 includes a base portion 12 and a cap portion 14 that is fluidly-connected to the base portion 12. The fluid retainer cartridge assembly 10 may optionally include a fluid filter 11 that may be connected to the base portion 12.

As will be explained in greater detail in the following disclosure (at FIGS. 18-22), the base portion 12 and the cap portion 14 collectively retain at least one (e.g., three) implement I (see, e.g., FIGS. 1A-1) while the base portion 12 guides an amount of fluid F, for example, raw milk (see, e.g., FIG. 1B) into a fluid-receiving void defined by the cap portion 14. If optionally included, the fluid filter 11 may filter the fluid F. Once the fluid F arrives in the fluid-receiving void of the cap portion 14, the fluid F contacts the at least one implement I. In an example, the at least one implement I may be a test strip assay and the fluid F may include a chemical analyte (e.g., a veterinary antibiotic, such as a beta-lactam or tetracycline) that chemically reacts with the at least one test strip assay I. In an example as seen in FIG. 1A, each implement I₁, I₂, I₃ of the plurality of implements I may include indicia markings, such as, for example, one or more of barcode data B, alphanumerical data # (e.g., letters and/or numbers), color data C or the like that may be read by an optical reader 136 (see, e.g., FIGS. 25-26) of an implement analyzing device 100 (see, e.g., FIG. 23) that can monitor, read and analyze the one or more implements I before, during or after being contacted with the fluid F. Preloaded cartridge assemblies 10 may include an identification marker on the cartridge itself that can be interpreted and used to identify the set of tests present. Barcode data B may include one-dimensional or multi-dimensional barcodes.

Although an exemplary fluid F may include, for example, raw milk as described above, other fluids F may be interfaced with the fluid retainer cartridge assembly 10. For example, other exemplary fluids F may include, but is not limited to: blood, saliva, corn fluid or the like. Furthermore, the fluid F may be interfaced with the fluid retainer cartridge assembly 10 at any desirable temperature, such as, for example, room temperature, a temperature that is lower than room temperature (as a result of, for example, cooling or chilling the fluid F) or a temperature that is higher than room temperature (as a result of, for example, warming or heating the fluid F).

Each of the base portion 12 and the cap portion 14 may be formed from a thermoplastic or other material suitable for injection molding, such as, acrylonitrile butadiene styrene (ABS plastic). Other exemplary materials may include polypropylene, polystyrene, nylon, polycarbonate, and thermoplastics infused with polymers (e.g., graphite, carbon fibers, glass-reinforced) to enhance thermal conductivity. The thermoplastic material may promote, for example, sufficient heat transfer of heat from an external heating source in order to warm or heat the fluid F that is disposed within the fluid retainer cartridge assembly 10.

Referring to FIGS. 2-7, the base portion 12 includes a body 16 that is generally defined by a front surface 16 _(F) (see, e.g., FIG. 2), a rear surface 16 _(R), (see, e.g., FIG. 3) a distal end surface 16 _(D) (see, e.g., FIG. 4), a proximal end surface 16 _(P) (see, e.g., FIG. 5), a first side surface 16 _(S1) (see, e.g., FIG. 6) and a second side surface 16 _(S2) (see, e.g., FIGS. 3 and 6). As seen in FIGS. 2-3, the base portion 12 is further generally defined by a length L₁₂ extending between the distal end surface 16 _(D) and the proximal end surface 16 _(P). The base portion 12 is yet even further generally defined by a width W₁₂ extending between the first side surface 16 _(S1) and the second side surface 16 _(S2).

Referring to FIG. 2, the front surface 16 _(F) of the body 16 of the base portion 12 generally defines more than one implement-receiving channel 18 (e.g., three implement-receiving channels 18 a-18 c) extending along a portion L_(12-P) of the length L₁₂ of the base portion 12. The more than one implement-receiving channel 18 may be defined by a first sidewall flange 20 a, a second sidewall flange 20 b, a first rib 22 a and a second rib 22 b.

The first sidewall flange 20 a extends away from the front surface 16 _(F) and is arranged proximate the first side surface 16 _(S1). The second sidewall flange 20 b extends away from the front surface 16 _(F) and is arranged proximate the second side surface 16 _(S2). The first rib 22 a extends away from the front surface 16 _(F) and is arranged proximate the first sidewall flange 20 a. The second rib 22 b extends away from the front surface 16 _(F) and is arranged proximate but spaced-apart from second sidewall flange 20 b.

The first sidewall flange 20 a is spaced apart from the first rib 22 a at a distance equal to a first portion W₁₂₋₁ of the width W₁₂ of the base portion 12 for defining a first implement-receiving channel 18 a of the more than one implement-receiving channels 18. The first rib 22 a is spaced apart from the second rib 18 b at a distance equal to a second portion W₁₂₋₂ of the width W₁₂ of the base portion 12 for defining a second implement-receiving channel 18 b of the more than one implement-receiving channels 18. The second rib 22 b is spaced apart from the second sidewall flange 20 b at a distance equal to a third portion W₁₂₋₃ of the width W₁₂ of the base portion 12 for defining a third implement-receiving channel 18 c of the more than one implement-receiving channels 18.

With continued reference to FIG. 2, the front surface 16 _(F) of the body 16 of the base portion 12 further defines an implement distal end retainer portion 24. The implement distal end retainer portion 24 extends across the width W₁₂ of the base portion 12 and connects the first sidewall flange 20 a to the second sidewall flange 20 b. Furthermore, the implement distal end retainer portion 24 may be further defined by a distal end 24 _(D) and a proximal end 24 _(P); the distal end 24 _(D) may be arranged at a distance D₂₄ away from the distal end surface 16 _(D) of the body 16 of the base portion 12 for defining an access port 26 that is sized for permitting insertion of, for example, a user's finger therein for grasping any of the one or more implements I for inserting or removing the one or more implements I from the more than one implement-receiving channels 18. The implement distal end retainer portion 24 may also include a series of friction ribs 25 that may assist a user in grasping the fluid retainer cartridge assembly 10 when inserting or removing the fluid retainer cartridge assembly 10 into/from an implement analyzing device 100 (see, e.g., FIG. 23), such as an optical reader 136 (seem e.g., FIGS. 25-26) that can monitor, read and analyze the one or more implements I before, during or after being contacted with the fluid F.

With reference to FIGS. 2 and 7, each of the first sidewall flange 20 a and the second sidewall flange 20 b may extend away from the front surface 16 _(F) of the body 16 of the base portion 12 at a substantially constant distance D₂₀ (see, e.g., FIG. 7) along the portion L_(12-P) of the length L₁₂ of the base portion 12. Each of the first rib 22 a and the second rib 22 b may extend away from the front surface 16 _(F) of the body 16 of the base portion 12 at a substantially constant distance D₂₂₋₁ (see, e.g., FIG. 7) along a first segment L_(12-P1) (see, e.g., FIG. 2) of the portion L_(12-P) of the length L₁₂ of the base portion 12. The first segment L_(12-P1) of the portion L_(12-P) of the length L₁₂ of the base portion 12 may be bound by a proximal end L_(12-P1D) and a distal end L_(12-P1D). In some examples, each of the first rib 22 a and the second rib 22 b may extend away from the front surface 16 _(F) of the body 16 of the base portion 12 at a progressively-increasing distance D₂₂₋₂ (see, e.g., FIG. 7) from the distal end L_(12-P1D) of the first segment L_(12-P1) of the portion L_(12-P) of the length L₁₂ of the base portion 12 along a second segment L_(12-P2) (see, e.g., FIG. 2) of the portion L_(12-P) of the length L₁₂ of the base portion 12 toward the proximal end 24 _(P) of the implement distal end retainer portion 24.

As seen in FIG. 2, a portion (i.e., a tongue portion 28) of the front surface 16 _(F) of the body 16 of the base portion 12 does not include any of the first sidewall flange 20 a, the second sidewall flange 20 b, the first rib 22 a and the second rib 22 b. In an example as seen in FIG. 1B, when the one or more implements I are interfaced with the fluid retainer cartridge assembly 10, the one or more implements I may extend out of the more than one implement-receiving channels 18 and over the tongue portion 28.

Referring to FIG. 2, the tongue portion 28 may be defined by a length L₂₈ extending between the proximal end L_(12-P1P) of the first segment L_(12-P1) of the portion L_(12-P) of the length L₁₂ of the base portion 12 and proximal-most/lower-most portion of the proximal end surface 16 _(P) of the body 16 of the base portion 12. In some instances, the proximal end surface 16 _(P) may include an arcuate shape that partially defines the tongue portion 28. Furthermore, proximal end surface 16 _(P) connects (see, e.g., dashed line X₂₈ extending across the tongue portion 28) the first side surface 16 _(S1) to the second side surface 16 _(S2). Yet even further, as see in FIG. 2, the first side surface 16 _(S1) is substantially parallel to the second side surface 16 _(S2) along the length L₂₈ of the tongue portion 28. Therefore, in an example, the tongue portion 28 may be generally defined by: (1) a substantially square or rectangular portion 28 a defined in part by the first side surface 16 _(S1) and the second side surface 16 _(S2) and (2) a substantially ‘half moon’ portion 28 b defined by the proximal end surface 16 _(P), which is demarcated from the substantially square or rectangular portion 28 a by the dashed line X₂₈.

Although the first sidewall flange 20 a, the second sidewall flange 20 b, the first rib 22 a and the second rib 22 b do not extend away from the front surface 16 _(F) of the body 16 of the base portion 12 defined by the tongue portion 28, a plurality of projections 30 extend away from the front surface 16 _(F) of the body 16 of the base portion 12 defined by the tongue portion 28 at a distance D₃₀ (see, e.g., FIG. 7). In some implementations, the plurality of projections 30 may be substantially cylindrical (or they may have another shape for evenly distributing and selectively flowing the fluid F, as described below), and may be linearly-arranged in a row (see, e.g., dashed line R₃₀ extending across the ‘half moon’ portion 28 b, which is substantially parallel to the dashed line X₂₈). Furthermore, the row R₃₀ of the plurality of projections 30 may extend from the ‘half moon’ portion 28 b of the tongue portion and may be arranged at a length L₃₀ (see, e.g., FIG. 2) away from the proximal end L_(12-P1P) of the first segment L_(12-P1) of the portion L_(12-P) of the length L₁₂ of the base portion 12.

In an example, as seen in FIG. 2, the plurality of projections 30 may be defined by a first projection 30 a, a second projection 30 b, a third projection 30 c, a fourth projection 30 d and a fifth projection 30 e. In some implementations, the plurality of projections 30 including the first-through-fifth projections 30 a-30 e may be arranged relative to the first-through-third implement-receiving channels 18 a-18 c as follows: (1) the first projection 30 a may be aligned with a center (see, e.g., dashed line C_(18a)) of the first portion W₁₂₋₁ of the width W₁₂ defining the first implement-receiving channel 18 a, (2) the second projection 30 b may be aligned with a center (see, e.g., dashed line C_(22a)) of the first rib 22 a that partially defines each of the first and second implement-receiving channels 18 a, 18 b, (3) the third projection 30 c may be aligned with a center (see, e.g., dashed line C_(18b)) of the second portion W₁₂₋₂ of the width W₁₂ defining the second implement-receiving channel 18 b, (4) the fourth projection 30 d may be aligned with a center (see, e.g., dashed line C_(22b)) of the second rib 22 b that partially defines each of the second and third implement-receiving channels 18 b, 18 c and (5) the fifth projection 30 e may be aligned with a center (see, e.g., dashed line C_(18c)) of the third portion W₁₂₋₃ of the width W₁₂ defining the third implement-receiving channel 18 c.

In an example, the tongue portion 28 may further define a fluid-flow passage 32 extending through a thickness T₁₆ (see, e.g., FIG. 7) of the body 16 of the base portion 12. The thickness T₁₆ of the body 16 of the base portion 12 (as defined by the tongue portion 28) is bound by the front surface 16 _(F) of the body 16 of the base portion 12 and the rear surface 16 _(R) of the body 16 of the base portion 12. Furthermore, as seen in FIGS. 2-3, the fluid-flow passage 32 may be defined by the substantially ‘half moon’ portion 28 b of the tongue portion 28. In some instances, the fluid-flow passage 32 may include a smaller, but substantially proportional ‘half-moon’ geometry compared to the ‘half moon’ portion 28 b of the tongue portion 28 and includes a maximum width W₃₂ (see, e.g., FIG. 3) that extends between an laterally-outward-most portion of each of the second projection 30 b and the fourth projection 30 d.

In yet another example, the tongue portion 28 may further define a fluid-flow guide rib 34. The fluid-flow guide rib 34 may extend away from the front surface 16 _(F) of the body 16 of the base portion 12 defined by the substantially ‘half moon’ portion 28 b of the tongue portion 28 at a distance D₃₄ (see, e.g., FIG. 7). Furthermore, as seen in FIG. 2, the fluid-flow guide rib 34 may include an arcuate shape and extend away from the front surface 16 _(F) of the body 16 of the base portion 12 defined by the substantially ‘half moon’ portion 28 b of the tongue portion 28 proximate the proximal end surface 16 _(P) of the body 16 of the base portion 12.

Referring to FIG. 1A, the fluid retainer cartridge assembly 10 may further define a fluid guide portion 36. In an example, the fluid guide portion 36 may be defined by a funnel portion 36 a formed by the base portion 12 and a fluid conduit portion 36 b formed by the cap portion 14.

Referring to FIGS. 3-7, the funnel portion 36 a is generally defined by a funnel body 38 that extends away from the rear surface 16 _(R) of the base portion 12. As seen in FIG. 3, the funnel body 38 may be defined by a distal surface 38 _(D), which may be defined, in part, by the distal surface 16 _(D) of the body 16 of the base portion 12, and a proximal surface 38 _(P). With continued reference to FIG. 3, the funnel body 38 may include a length defined approximately by the portion L_(12-P) of the length L₁₂ of the base portion 12. The funnel body 38 may be defined by a width W₃₉ that narrows for at least a portion of the length L_(12-P) of the funnel body 38 as the funnel body 38 extends from the distal surface 38 _(D) to the proximal surface 38 _(P).

Referring to FIG. 7, the funnel body 38 is generally defined by an inner surface 38 _(I) and an outer surface 38 _(O). The inner surface 38 _(I) is arranged in an opposing relationship with respect to the rear surface 16 _(R) of the body 16 of the base portion 12 and forms a fluid-flow passage 40 extending through the funnel body 38. Access to the fluid-flow passage 40 is formed by an upstream opening 42 (see, e.g., FIGS. 4 and 7) that permits entry of the fluid F into the funnel body 38 and a downstream opening 44 (see, e.g., FIGS. 4 and 5) that permits the fluid F to exit the funnel body 38.

The fluid-flow passage 40 may be defined by an arcuate channel having a radius R₄₀ or radial geometric component. Furthermore, as seen in FIG. 7, the radius R₄₀ may be greater near the distal surface 38 _(D) of the funnel body 38 such that the upstream opening 42 forms a larger opening or mouth portion of the fluid-flow passage 40 of the funnel body 38 than that of the downstream opening 44, which may form a relatively smaller opening or throat portion of the fluid-flow passage 40 of the funnel body 38.

Referring to FIGS. 3 and 5, the rear surface 16 _(R) of the base portion 12 may also define a cap-retainer portion 46. The cap-retainer portion 46 may defined by a pair of protrusions including a first protrusion 46 a and a second protrusion 46 b that extend away from the rear surface 16 _(R) of the base portion 12. The first protrusion 46 a and the second protrusion 46 b may be respectively arranged near opposite sides of the funnel body 38 and near the proximal surface 38 _(P) of the funnel body 38. Each of the first protrusion 46 a and the second protrusion 46 b may be defined by a ramp surface 48 and latch surface 50 (FIG. 15A).

Referring to FIGS. 8-13, the cap portion 14 of the fluid retainer cartridge assembly 10 includes a body 52 and a tongue-receiving housing 54 connected to the body 52. The body 52 is generally defined by a front surface 52 _(F), a rear surface 52 _(R), a distal end surface 52 _(D), a proximal end surface 52 _(P), a first side surface 52 _(S1) and a second side surface 52 _(S2). The cap portion 14 is further generally defined by a length L₁₄ (see, e.g., FIGS. 8-9 and 12-13) extending between the distal end surface 52 _(D) and the proximal end surface 52 _(P). The cap portion 14 is yet even further generally defined by a width W14 (see, e.g., FIGS. 8-11) extending between the first side surface 52 _(S1) and the second side surface 52 _(S2).

As seen in FIG. 8, the tongue-receiving housing 54 may be defined by an implement proximal end retainer portion 56 and a flange portion 58 defined by a first sidewall flange segment 58 a, a second sidewall flange segment 58 b and an arcuate flange segment 58 c. The implement proximal end retainer portion 56 extends across a width W14 of the base portion 14 and is connected to each of the first sidewall flange segment 58 a, the second sidewall flange segment 58 b and the arcuate flange segment 58 c. The implement proximal end retainer portion 56 extends away from the arcuate flange segment 58 c toward the distal end surface 52 _(D) of the body 52 at a length L₅₆; the length L₅₆ of the implement proximal end retainer portion 56 may be equal to approximately half of the length L₁₄ of the cap portion 14.

With continued reference to FIG. 8, the first sidewall flange segment 58 a extends away from the front surface 52 _(F) and is arranged proximate the first side surface 52 _(S1). The second sidewall flange segment 58 b extends away from the front surface 52 _(F) and is arranged proximate the second side surface 52 _(S2). The arcuate flange segment 58 c extends away from the front surface 52 _(F) and is arranged proximate the proximal surface 52 _(P).

Referring to FIG. 13, the body 52 of the cap portion 14 may include a substantially constant thickness T₅₂. As seen in FIGS. 8-13, the body 52 defined by the substantially constant thickness T₅₂ is not substantially planar, and, as a result, the body 52 may form an arcuate-shaped channel 60 (see, e.g., FIGS. 8, 10, 13) defined by a radius R₆₀ (see, e.g., FIGS. 10, 13) or radial geometric component extending into the front surface 52 _(F) of the body 52, which results in the rear surface 52 _(R) of the body 52 defining an arcuate projection.

Referring to FIGS. 9 and 12-13, the arcuate-shaped channel 60 may be defined by a length L₆₀ that extends along a portion of the length L₁₄ of the cap portion 14 from the distal end surface 52 _(D) of the body 52 toward the proximal end surface 52 _(P) of the body 52. Furthermore, a remainder of the length L₁₄ of the cap portion 14 where the arcuate-shaped channel 60 is not formed is shown generally at L₆₀′. Yet even further, as seen in FIG. 13, a portion L_(60-P) of the length L₆₀ of the arcuate-shaped channel 60 extends along a portion of the length L₅₆ of the implement proximal end retainer portion 56.

Referring to FIGS. 8-9, a pair of protrusion-receiving passages 62 extend through the thickness T₅₂ of the body 52. The pair of protrusion-receiving passages 62 may defined by a first protrusion-receiving passage 62 a and a second protrusion-receiving passage 62 b. The first protrusion-receiving passage 62 a and the second protrusion-receiving passage 62 b may be respectively arranged near opposite sides of the arcuate-shaped channel 60.

As seen in FIGS. 10 and 13, the cap portion 14 forms a fluid-receiving void 64. The fluid-receiving void 64 is generally defined by an inner surface 56 _(I) of the implement proximal end retainer portion 56, an inner surface 581 of the arcuate flange segment 58 c, a portion of an inner surface 58 a 1, 58 b ₁ of each of the first sidewall flange segment 58 a and the second sidewall flange segment 58 b that extends along the length L₅₆ of the implement proximal end retainer portion 56, and a portion 52 _(F-P) of the front surface 52 _(F) that extends along the length L₅₆ of the implement proximal end retainer portion 56.

Referring to FIGS. 14A-15B, a method for forming the fluid retainer cartridge assembly 10 is described. In a first optional step, as seen at FIGS. 14A and 15A, the fluid filter 11 may be inserted on the front surface 16 _(F) in the substantially half-moon portion 28 b of the tongue portion 28 and between projections 30 and fluid-flow guide rib 34 (i.e., as described herein-below, the fluid filter 11 may be inserted in a downstream fluid-receiving void 64 b). The fluid filter 11 may be sized and configured to be arranged in this location in a friction-fit relationship. Furthermore, the fluid filter 11 may be sized to have a thickness Ti that is similar to the height of the projections 30 and/or fluid-flow guide rib 34 above the front surface 16 _(F), e.g., the distance D₃₀ less the thickness T₁₆, or the distance D₃₄ less the thickness T₁₆ (FIG. 7). Although an implementation of the fluid retainer cartridge assembly 10 may include the fluid filter 11, the fluid filter 11 may be omitted from the design of the fluid retainer cartridge assembly 10.

Although an implementation of the fluid retainer cartridge assembly 10 may include one fluid filter 11 as described above, the fluid retainer cartridge assembly 10 may include one or more second filters. In an example, a second filter or pre-filter 11 a may be connected to the base portion 12. Because the pre-filter 11 a is located upstream of the filter 11, the pre-filter 11 a may be referred to as an upstream filter and the filter 11 may be referred to as a downstream filter. In an implementation, the pre-filter 11 a may be disposed within the fluid-flow passage 40 extending through the funnel body 38 proximate or near the distal surface 38 _(D) of the funnel body 38. Therefore, the pre-filter 11 a may filter a ‘dirty’ fluid F prior to the fluid F being passed through the fluid filter 11.

As seen in FIGS. 14A and 15A, the distal end surface 52 _(D) of the body 52 of the cap portion 14 is axially aligned with the proximal end surface 16 _(P) of the body 16 of the base portion 12. Furthermore, as seen in FIGS. 14A and 15A, the tongue portion 28 of the base portion 12 is axially aligned with the fluid-receiving void 64 formed by the tongue-receiving housing 54 of the cap portion 14. When the base portion 12 and the cap portion 14 are axially aligned as described above, the fluid-flow passage 40 extending through the funnel body 38 of the base portion 12 is axially aligned with the arcuate-shaped channel 60 formed by the body 52 of the cap portion 14.

With reference to FIG. 14A, the first side surface 16 _(S1) defining a proximal end 20 a _(P) of the first sidewall flange 20 a of the base portion 12 may define a recess that corresponds to a projection defined by a distal end 58 a _(D) of the first sidewall flange segment 58 a of the cap portion 14. Similarly, as seen in FIG. 15A, the second side surface 16 _(S2) defining a proximal end 20 b _(P) of the second sidewall flange 20 b of the base portion 12 may define a recess that corresponds to a projection defined by a distal end 58 b _(D) of the second sidewall flange segment 58 b of the cap portion 14.

Furthermore, as seen in FIG. 15A, when the base portion 12 and cap portion 14 are axially aligned as described above, the cap-retainer portion 46 (of the base portion 12) defined by the first protrusion 46 a and the second protrusion 46 b are axially aligned with the pair of protrusion-receiving passages 62 (of the cap portion 14) defined by the first protrusion-receiving passage 62 a and the second protrusion-receiving passage 62 b. As the tongue portion 28 of the base portion 12 is inserted into the fluid-receiving void 64 of the cap portion 14, the ramp surface 48 of each of the first protrusion 46 a and the second protrusion 46 b contacts and rides adjacent the front surface 52 _(F) (proximate the distal end surface 52 _(D)) of the body 52 for respectively advancing each of the first protrusion 46 a and the second protrusion 46 b into the first protrusion-receiving passage 62 a and the second protrusion-receiving passage 62 b. Just after the ramp surface 48 of each of the first protrusion 46 a and the second protrusion 46 b has been respectively aligned with the first protrusion-receiving passage 62 a and the second protrusion-receiving passage 62 b, the body 52 (proximate the distal end surface 52 _(D)) of the cap portion 14 flexes over the latch surface 50 of each of the first protrusion 46 a and the second protrusion 46 b for removably-attaching the cap portion 14 to the base portion 12 as seen in FIGS. 14B and 15B.

Referring to FIGS. 16-17, the base portion 12 and the cap portion 14 are shown in a removably-attached configuration after the first protrusion 46 a and the second protrusion 46 b are arranged within the first protrusion-receiving passage 62 a and the second protrusion-receiving passage 62 b. With reference to FIG. 17, the fluid-flow passage 40 extending through the funnel body 38 of the base portion 12 is fluidly-connected to the arcuate-shaped channel 60 formed by the body 52 of the cap portion 14 for forming an axial fluid conduit 66 of the fluid retainer cartridge assembly 10. Furthermore, as seen in FIG. 17, after the first protrusion 46 a and the second protrusion 46 b are arranged within the first protrusion-receiving passage 62 a and the second protrusion-receiving passage 62 b for removably-attaching the base portion 12 to the cap portion 14, the tongue portion 28 of the base portion 12 is fully axially disposed within the fluid-receiving void 64 formed by the tongue-receiving housing 54 of the cap portion 14 such that the tongue portion 28 fluidly-divides the fluid-receiving void 64 into an upstream fluid-receiving void 64 a and the downstream fluid-receiving void 64 b. The upstream fluid-receiving void 64 a is in fluid communication with the downstream fluid-receiving void 64 b by way of the fluid-flow passage 32 of the tongue portion 28.

If the fluid filter 11 is disposed within the downstream fluid-receiving void 64 b, any fluid F that passes from the upstream fluid-receiving void 64 a to the downstream fluid-receiving void 64 b by way of the fluid-flow passage 32 will be filtered by the fluid filter 11; in such an implementation, the upstream fluid-receiving void 64 a may be referred to as an unfiltered reservoir portion of the fluid-receiving void 64 and the downstream fluid-receiving void 64 b may be referred to as a filtered reservoir portion of the fluid-receiving void 64. However, if the fluid filter 11 is not disposed within the downstream fluid-receiving void 64 b, any fluid F that enters the downstream fluid-receiving void 64 b from the upstream fluid-receiving void 64 a by way of the fluid-flow passage 32 of the tongue portion 28 is not filtered.

Referring to FIGS. 1A-1B and 18, a plurality of implements I (e.g., a plurality of test strip assays) are interfaced with the fluid retainer cartridge assembly 10. The plurality of test strip assays I includes three test strip assays, being: a first test strip assay I₁, a second test strip assay I₂ and a third test strip assay I₃.

As seen in FIGS. 1A and 18, the plurality of test strip assays I are disposed into the fluid retainer cartridge assembly 10 by way of the access port 26 formed by the body 16 of the base portion 12 such that the plurality of test strip assays I are arranged within the plurality of implement-receiving channels 18. In an example, the plurality of test strip assays I may be arranged within the plurality of implement-receiving channels 18 as follows: (1) the first test strip assay I₁ is arranged within the first implement-receiving channel 18 a, (2) the second test strip assay I₂ is arranged within the second implement-receiving channel 18 b and (3) the third test strip assay I₃ is arranged within the third implement-receiving channel 18 c.

Referring to FIG. 18, insertion of the plurality of test strip assays I into the fluid retainer cartridge assembly 10 ceases once a proximal end I_(1P), I_(2P), I_(3P) of each test strip assay I₁, I₂, I₃ engages a corresponding projection 30 a, 30 c, 30 e of the plurality of projections 30. For example, as seen in FIG. 18: (1) the proximal end lip of the first test strip assay I engages the first projection 30 a that is aligned with the center C_(18a) (see, e.g., FIG. 2) of the first portion W₁₂₋₁ of the width W₁₂ of the base portion 12 that defines the first implement-receiving channel 18 a, (2) the proximal end I_(2P) of the second test strip assay I₂ engages the third projection 30 c that is aligned with the center C_(18b) (see, e.g., FIG. 2) of the second portion W₁₂₋₂ of the width W₁₂ of the base portion 12 that defines the second implement-receiving channel 18 b and (3) the proximal end I_(3P) of the third test strip assay I₃ engages the fifth projection 30 e that is aligned with the center C_(18c) (see, e.g., FIG. 2) of the third portion W₁₂₋₃ of the width W₁₂ of the base portion 12 that defines the third implement-receiving channel 18 c.

As seen in FIG. 18, each test strip assay I₁, I₂, I₃ of the plurality of test strip assays I includes a width W₁ and a length L₁. The width W₁ of each test strip assay I₁, I₂, I₃ is respectively approximately equal to the width portion W₁₂₋₁, W₁₂₋₂, W₁₂₋₃ (see, e.g., FIG. 2) of the width W₁₂ of the base portion 12 that defines each implement-receiving channel 18 a, 18 b, 18 c of the plurality of implement-receiving channels 18. With reference to FIGS. 1B and 18, the length L₁ of each test strip assay I₁, I₂, I₃ is selectively sized such that when the proximal end I_(1P), I_(2P), I_(3P) of each test strip assay I₁, I₂, I₃ engages a corresponding projection 30 a, 30 c, 30 e of the plurality of projections 30, a distal end I_(1D), I_(2D), I_(3D) of each test strip assay I₁, I₂, I₃ is accessible at the access port 26 for permitting, for example, insertion of a user's finger therein for grasping any of the first, second or third test strip assays I₁, I₂, I₃ for inserting or removing any of the first, second or third test strip assays I₁, I₂, I₃ from any of the first, second or third implement-receiving channels 18 a, 18 b, 18 c.

Referring to FIGS. 1B and 19-21A, fluid F is poured into the fluid retainer cartridge assembly 10. As seen in FIGS. 1B, 19 and 19A, the fluid F initially enters the axial fluid conduit 66 of the fluid retainer cartridge assembly 10 by way of the upstream opening 42 of the funnel body 38 formed by the base portion 12. The fluid F passes through the fluid-flow passage 40 of the funnel body 38 of the base portion 12 and subsequently exits the fluid-flow passage 40 of the funnel body 38 of the base portion 12 at the downstream opening 44. The fluid F then enters the arcuate-shaped channel 60 formed by the body 52 of the cap portion 14 that is in fluid communication with the fluid-flow passage 40 of the funnel body 38 of the base portion 12 at the downstream opening 44 such that the fluid F ultimately arrives at the upstream fluid-receiving void 64 a of the fluid-receiving void 64. In an example, as seen in FIG. 19A, fluid F_(O) (which is an amount of the fluid F that exceeds the volume of the fluid-receiving void 64) exits the fluid retainer cartridge assembly 10 by spilling over a fluid overflow edge 68, which may be a portion of the distal end surface 52 _(D), formed by the front surface 52 _(F) of the body 52 of the cap portion 14.

As seen in FIGS. 20 and 20A, the fluid F may radially pass from the upstream fluid-receiving void 64 a of the fluid-receiving void 64 and into the downstream fluid-receiving void 64 b of the fluid-receiving void 64. As seen in FIGS. 20 and 20A, the fluid filter 11 is shown optionally inserted into the downstream fluid-receiving void 64 b for filtering the fluid F as the fluid F migrates radially through the fluid filter 11 from the upstream fluid-receiving void 64 a into the downstream fluid-receiving void 64 b.

As seen in FIGS. 21 and 21A, after the fluid F arrives in the downstream fluid-receiving void 64 b of the fluid-receiving void 64 and moves around projections 30, the fluid F comes into contact with the proximal end I_(1P), I_(2P), I_(3P) of each test strip assay I₁, I₂, I₃ and fluid F is drawn up each test strip assay I₁, I₂, I₃, for example, by capillary action. The shape, quantity and arrangement (e.g., centering along the dashed lines C_(18a), C_(18b), C_(18c), C_(22a), C_(22b) of FIG. 2) of the plurality of projections 30 may assist in evenly distributing and selectively flowing the fluid F about the proximal end I_(1P), I_(2P), I_(3P) of each test strip assay I₁, I₂, I₃ for adequately dosing each test strip assay I₁, I₂, I₃ with a sufficient amount of fluid F.

Referring to FIG. 22, in one use of the fluid retainer cartridge assembly 10, after being contacted with the fluid F, each test strip assay I₁, I₂, I₃ may include a result region R configured to provide a detectable signal DS (e.g., a color change or intensity information) indicating the presence and/or concentration of a chemical analyte within the fluid (F) when the fluid (F) is in contact with the result region R; and the detectable signal DS may be determined by exposing each test strip assay I₁, I₂, I₃ to an optical reader 136 (see, e.g., FIGS. 25-26) of an implement analyzing device 100 (see, e.g., FIG. 23) that can monitor, read and analyze the one or more test strip assays I₁, I₂, I₃ during or after being contacted with the fluid F. As used herein, the detectable signal DS is associated with color and/or intensity information within the result region R (FIGS. 1A and 22) located on each of the one or more test strip assays I₁, I₂, I₃. Exposure of each test strip assay I₁, I₂, I₃ to an optical reader 136 of an implement analyzing device 100 may be permitted by a viewing window or viewing port 70 of the fluid retainer cartridge assembly 10. With reference to FIG. 1B, the viewing window or viewing port 70 is defined by an absence of material of one or both of the base portion 12 and the cap portion 14. In an example, the viewing window or viewing port 70 is generally bound by: (1) the first sidewall flange 20 a of the front surface 16 _(F) of the body 16 of the base portion 12, (2) the second sidewall flange 20 b of the front surface 16 _(F) of the body 16 of the base portion 12, (3) the proximal end 24 _(P) of the implement distal end retainer portion 24 the front surface 16 _(F) of the body 16 of the base portion 12 and (4) the fluid overflow edge 68 formed by the front surface 52 _(F) of the body 52 of the cap portion 14.

In other examples (as shown in FIGS. 7 and 13), the inner surface 38 _(I) of the funnel body 38 formed by the base portion 12, the portion 52 _(F-P) of the front surface 52 _(F) that extends along the length L₅₆ of the implement proximal end retainer portion 56, and/or the inner surface 56 _(I) of the implement proximal end retainer portion 56 may include an optional dried reagent 72 disposed thereon. Such reagents may include acids, bases, buffers, surfactants, dyes, colorometric signaling agents, fluorometric signaling agents, antibodies, enzymes, receptors, antigens, cofactors, chemical filtration agents, anticoagulants, blocking agents, chelating agents, and leaching agents.

In yet another implementation, the fluid retainer cartridge assembly 10 may include a seal 74 (not shown), which may be formed from, for example, a foil material. The seal 74 may be disposed over, adjacent, proximate or near the distal surface 38 _(D) of the funnel body 38. The seal 74 may serve one or more purposes, for example, to prevent contamination of the inner surface 38 _(I) of the funnel body 38 and/or for retention of dried reagent 72 on the inner surface 38 _(I) of the funnel body 38 of base portion 12.

Referring to FIG. 23, an implement analyzing device 100 is shown generally at 100. The implement analyzing device 100 is sized for receiving more than one fluid retainer cartridge assembly 10, which has been described above at FIGS. 1A-22. As seen in FIG. 23, the more than one fluid retainer cartridge assembly 10 may be, for example: a first fluid retainer cartridge assembly 10 ₁; a second fluid retainer cartridge assembly 10 ₂; and a third fluid retainer cartridge assembly 10 ₃. The first fluid retainer cartridge assembly 10 ₁, the second fluid retainer cartridge assembly 10 ₂ and the third fluid retainer cartridge assembly 10 ₃ may be collectively referred to as a plurality of fluid retainer cartridge assemblies 10 _(P).

The exemplary first fluid retainer cartridge assembly 10 ₁, the exemplary second fluid retainer cartridge assembly 10 ₂ and the exemplary third fluid retainer cartridge assembly 10 ₃ that may be interfaced with the implement analyzing device 100 may be substantially similar to the fluid retainer cartridge assembly 10 described above at FIGS. 1A-22. Although the following disclosure is directed to the exemplary fluid retainer cartridge assemblies 10 ₁, 10 ₂, 10 ₃ being interfaced with the implement analyzing device 100, the implement analyzing device 100 is not limited to being interfaced with the exemplary fluid retainer cartridge assemblies 10 ₁, 10 ₂, 10 ₃; as such, the functionality of the implement analyzing device 100 may remain the same when other fluid retainer cartridge assemblies having different shapes or sizes are interfaced with the implement analyzing device 100.

In association with what has been described above at FIGS. 1A-22, the exemplary fluid retainer cartridge assemblies 10 ₁, 10 ₂, 10 ₃ are each sized for containing a plurality of implements I, such as, for example, a first test strip assay I₁, a second test strip assay I₂ and a third test strip assay I₃. Furthermore, because the implement analyzing device 100 is sized for receiving more than one fluid retainer cartridge assembly (e.g., three fluid retainer cartridge assemblies 10 ₁, 10 ₂, 10 ₃), and, if each of the first fluid retainer cartridge assembly 10 ₁, the second fluid retainer cartridge assembly 10 ₂ and the third fluid retainer cartridge assembly 10 ₃ are respectively loaded with a plurality of implements I such as, for example, a first test strip assay I₁, a second test strip assay I₂ and a third test strip assay I₃, each of the first fluid retainer cartridge assembly 10 ₁, the second fluid retainer cartridge assembly 10 ₂, and the third fluid retainer cartridge assembly 10 ₃ may be said to contain a plurality of test strip assays I₁-I₃ (defined respectively, for example, by: a first plurality of test strip assays I₁-I₃ contained by the first fluid retainer cartridge assembly 10 ₁; a second plurality of test strip assays I₁-I₃ contained by the second fluid retainer cartridge assembly 10 ₂; and a third plurality of test strip assays I₁-I₃ contained by the third fluid retainer cartridge assembly 10 ₃). Therefore, in use, the implement analyzing device 100 may simultaneously, sequentially, selectively or randomly analyze all or any test strip assay I₁, I₂, I₃ that is secured by all or any of the first fluid retainer cartridge assembly 10 ₁, the second fluid retainer cartridge assembly 10 ₂ and the third fluid retainer cartridge assembly 10 ₃.

In an example, simultaneous analysis of the first plurality of test strip assays I₁-I₃, the second plurality of test strip assays I₁-I₃ and the third plurality of test strip assays I₁-I₃ by the implement analyzing device 100 may expedite an analysis of what may otherwise be one analysis of one plurality of test strip assays I₁-I₃ (if the implement analyzing device 100 was configured to only receive one fluid cartridge retainer assembly). In an example, the implement analyzing device 100 may conduct simultaneous analysis of one implement (e.g., the first test strip assay I₁) of the first plurality of test strip assays I₁-I₃, the second plurality of test strip assays I₁-I₃ and the third plurality of test strip assays I₁-I₃; therefore, if desired, a user may comparatively study three unique species studies (e.g., that is associated with a unique sample associated with each first test strip assay I₁ of: the first plurality of test strip assays I₁-I₃; the second plurality of test strip assays I₁-I₃; and the third plurality of test strip assays I₁-I₃) of a genus study (e.g., a genus test associated with a common sample type related to the each first test strip assay I₁ and not each of the second test strip assay I₂ and each of the third test strip assay I₃) in one instance.

Referring to FIGS. 23 and 24A-24B, the implement analyzing device 100 includes a support member 102 and a housing 104 connected to the support member 102. As seen in FIG. 25, each of the support member 102 and the housing 104 may respectively form one or more fastener passages 106, 108 that correspond to one another that are sized for receiving one or more fasteners 110. The one or fasteners 110 permit selective attachment of the housing 104 to the support member 102.

With reference to FIGS. 23, 24A-24B, 25 and 26, the support member 102 may define an outer surface 112 and an inner surface 114 (see, e.g., FIGS. 25-26). Similarly, the housing 104 may define an outer surface 116 and an inner surface 118 (see, e.g., FIGS. 25-26). The inner surface 114 of the support member 102 and the inner surface 118 of the housing 104 cooperate to form a cavity 120 (see, e.g., FIGS. 25-26).

As seen in FIGS. 23, 24A-24B, 25, 26 and 32-34, the implement analyzing device 100 may further include a cartridge receiver 122 disposed within the cavity 120. In an example, the cartridge receiver 122 is secured to the inner surface 114 of the support member 102.

Referring to FIGS. 23, 26 and 32, the cartridge receiver 122 includes a body 124 defining at least one first opening 126 and at least one second opening 128 (see, e.g., FIG. 32). The at least one first opening 126 formed by the body 124 of the cartridge receiver 122 is aligned with a cartridge receiver passage 130 (see, e.g., FIG. 23) extending through a thickness T₁₀₄ (see, e.g., FIG. 26) of the housing 104 that is bound by the outer surface 116 of the housing 104 and an inner surface 118 of the housing 104. As seen in FIG. 26, the cartridge receiver passage 130 formed by the housing 104 permits access to the cartridge receiver 122 that is substantially contained within the cavity 120.

With reference to FIG. 23, the at least one first opening 126 of the body 124 of the cartridge receiver 122 may be defined by: a first cartridge receiving opening 126 a; a second cartridge receiving opening 126 b; and a third cartridge receiving opening 126 c. The first cartridge receiving opening 126 a may be sized for removable-insertion of the first fluid retainer cartridge assembly 10 ₁ within the body 124 of the cartridge receiver 122. The second cartridge receiving opening 126 b may be sized for removable-insertion of the second fluid retainer cartridge assembly 10 ₂ within the body 124 of the cartridge receiver 122. The third cartridge receiving opening 126 c may be sized for removable-insertion of the third fluid retainer cartridge assembly 10 ₃ within the body 124 of the cartridge receiver 122.

With reference to FIG. 25, in one embodiment, the at least one second opening 128 formed by the body 124 of the cartridge receiver 122 is contained within the cavity 120 and not accessible from any opening or passage formed by the housing 104. As seen in FIGS. 25 and 32, the at least one second opening 128 may be defined by a first cartridge viewing window 128 a, a second cartridge viewing window 128 b and a third cartridge viewing window 128 c. In one embodiment, each of the first cartridge viewing window 128 a, the second cartridge viewing window 128 b and the third cartridge viewing window 128 c may include a shape corresponding to the viewing window 70 (see, e.g., FIG. 1B) of each of the first fluid retainer cartridge assembly 10 ₁, the second fluid retainer cartridge assembly 10 ₂ and the third fluid retainer cartridge assembly 10 ₃.

With reference to FIGS. 25-26, the implement analyzing device 100 may further include an imaging device support member 132 disposed within the cavity 120. In an example, the imaging device support member 132 is secured to or integrally extends from the inner surface 114 of the support member 102.

In an example, the imaging device support member 132 supports an imaging device integrated circuit (IC) 134 that includes an imaging device 136. With reference to FIG. 26, the imaging device support member 132 is deliberately sized for arranging the imaging device 136 (and, correspondingly, the imaging device IC 134) away from the inner surface 114 of the support member 102 at a distance D₁₃₆. With reference to FIGS. 25-26, the resulting distance D₁₃₆ is sufficient for arranging imaging device 136 in alignment with a region (see, e.g., dashed line box R₁₂₈ in FIGS. 25 and 33) of the at least one second openings 128 a, 128 b, and 128 c formed by the body 124 of the cartridge receiver 122. To put it another away, the imaging device 136 is arranged to capture image data 141 (FIG. 35) within a field of view directed toward the second openings 128 a, 128 b, and 128 c formed through the body 124 of the cartridge receiver 122.

By aligning the imaging device 136 with the region R₁₂₉ of the at least one second opening 128 formed by the body 124 of the cartridge receiver 122, an imaging device 136 of the imaging device IC 134 is able to see/view/image/read the detectable signal DS (see, e.g., FIG. 22) formed by one or more of the test strip assays I₁, I₂, I₃ after the one or more test strip assays I₁, I₂, I₃ is/are contacted with the fluid F. And with the field of view (dashed line box R₁₂₈), the imaging device 136 may capture image data 141 from any and all test strip assays I loaded into a cartridge assembly 10 in the cartridge receiver 122. For instance, the image data 141 captured by imaging device 136 may include detectable signal DS (e.g., color and/or intensity information) from result region R located on the one or more test strip assays I₁, I₂, I₃ in contact with the fluid F. In an example, the imaging device 136 may be a complementary metal oxide semiconductor (CMOS) sensor. In other examples, a lens (not shown) may be mounted to or arranged over the CMOS sensor 136.

Referring to FIG. 26, the implement analyzing device 100 may further include an integrated circuit support member 138 disposed within the cavity 120. In an example, the integrated circuit support member 138 is secured to or is integral with the inner surface 114 of the support member 102. The integrated circuit support member 138 may secure or support an implement analyzing device integrated circuit (IC) 140. In an example, the implement analyzing device IC 140 may include embedded Linux software and a 1-GHz Sitara processor.

Referring to FIG. 35, the implement analyzing device IC 140 is coupled to the imaging device IC 134 by a communication link 142 (e.g., a flex cable) for communicating one or more readings (e.g., any of the detectable signals DS, barcodes B, and the like) in the image data 141 captured by the imaging device 136 to the implement analyzing device IC 140. Once the one or more readings (e.g., any of the detectable signals DS, barcodes B and the like) in the image data 141 is received by the implement analyzing device IC 140, the implement analyzing device IC 140 may analyze and subsequently interpret the one or more readings (e.g., any of the detectable signals DS, barcodes B and the like) for a user.

Referring back to FIGS. 23 and 24A-24B, in addition to the cartridge receiver passage 130, one or both of the support member 102 and the housing 104 may further defined a plurality of other passages 144-150 extending through a thickness T₁₀₂ (see, e.g., FIG. 26) of the support member 102 or the thickness T₁₀₄ of the housing 104. Like the cartridge receiver passage 130, the plurality of other passages 144-150 may extend through the thickness T₁₀₂ of the support member 102 or the thickness T₁₀₄ of the housing 104. The plurality of other passages 144-150 may include, but is not limited to: a user interface passage 144; one or more data input passages 146; one or more data input/output passages 148; one or more power passages 150 and the like. Furthermore, one or both of the support member 102 and the housing 104 may form a fluid overflow passage 152 (see, FIG. 26).

As seen in FIGS. 23 and 24A-24B, the user interface passage 144 may be sized for permitting access to a user interface 153 displayed on a screen 154. The screen 154 may be a touchscreen, which may be disposed within the cavity 120. At least a portion of a perimeter of the touchscreen 154 may be disposed adjacent or otherwise secured to the inner surface 118 of the housing 104 such that a user may access and read the touchscreen 154 by way of the user interface passage 144. Referring to FIG. 35, the touchscreen 154 may be communicatively coupled to one or more of the imaging device IC 134 and the implement analyzing device IC 140 by a communication link 156. In some examples, data processing hardware 143 at the implement analyzing device IC 140 executes the user interface 153 on the screen 154 for displaying a test result 190 associated with one or more test strip assays I.

In an example, the touchscreen 154 may be a capacitive touch touchscreen. The user interface may be a graphical user interface 153 displayed on the touchscreen 154 for conveying status of a test step being conducted, the test result 190 or the like. Furthermore, a user may interact with the graphical user interface 153 by touching the touchscreen 154. For instance, the user may provide data input or selections to software being executed by the data processing hardware 143 of the implement analyzing device IC 140.

As seen in FIGS. 23, 24A-24B and 27, the one or more data input passages 146 may be sized for permitting access to an optical scanner 158. In an example, the optical scanner 158 may be permitted to scan features or barcode data (e.g., one or more barcodes B) of items (e.g., one or more of the test strip assays I₁, I₂, I₃) arranged externally of the cavity 120. Referring to FIG. 35, the optical scanner 158 may be communicatively coupled to one or more of the imaging device IC 134 and the implement analyzing device IC 140 by a communication link 160. In some examples, the data processing hardware 143 receives barcode data B scanned by the optical scanner 158 that is associated with one or more of the test strip assays I₁, I₂, I₃; determines a unique test strip identifier 147 for each test strip assay I₁, I₂, I₃ based on the scanned barcode data; and retrieves from memory hardware 145 (which is in communication with the data processing hardware 143), test information 149 associated with each of the one or more of the test strip assays I₁, I₂, I₃. The test information 149 may include at least one of a test strip assay type, a test/analysis type, a desired temperature of the fluid F, an analysis duration, and any other information that may be pertinent. As used herein, the analysis duration may correspond to a time threshold or prescribed period of time indicating a minimum duration required for the fluid F to be in contact with the result region R of the test strip assay I associated with the obtained test information 149 before obtaining a corresponding test result 19 (e.g., a presence and/or concentration of the chemical analyte within the fluid F).

Additional uses for the optical scanner 158 may include scanning sample IDs and Lot ID data. Sample IDs are generated by a user to identify a sample fluid F being used. Additional uses for the optical scanner 158 may include scanning testing location information, user information, and any additional information that can be used for testing. The optical scanner 158 may also be used to change the mode of the reader (i.e., Demo mode), to unlock new features, or as a security feature to unlock the reader or specific reader functionality when the user scans a specific barcode.

As seen FIG. 24B, passages 148 may be sized for housing any type of data input/output port 162 such as, for example, one or more universal serial bus (USB) ports 162 a. Furthermore, the implement analyzing device IC 140 may also include an on-board USB port; in an implementation, the on-board USB port may be connected to a Wi-Fi dongle (not shown) to permit wireless communication with the implement analyzing device IC 140 (in order to, e.g., permit wireless uploading of a test result or downloading software updates). Referring to FIG. 35, the one or more data input/output ports 162 may be communicatively coupled to one or more of the imaging device IC 134 and the implement analyzing device IC 140 by a communication link 164.

Although the data input/output passages 148 may be sized for housing one or more USB ports 162 a, the data input/output passages 148 may be sized for housing other types of data ports 162. In an example, the data input/output passages 148 may be sized for housing one or more secure digital (SD) card ports 162 b. Thus, the data port 162 may include memory hardware 151 external to the implement analyzing device IC 140, in addition to, or in lieu of, the memory hardware 151 located at the implement analyzing device IC 140. In another example, the data input/output passages 148 may be sized for housing an Ethernet port 162 c for hardwire-connecting the implement analyzing device IC 140 to, for example, a router/wireless router for Internet access in the event that Wi-Fi is not available.

Referring to FIGS. 23 and 24A, the one or more power passages 150 may be sized for permitting insertion of a power cord 166 (see, e.g., FIG. 35). The power cord 166 may couple a power source P (e.g., a wall outlet, battery or the like) to one or more of the imaging device IC 134 and the implement analyzing device IC 140. Although a power cord 166 may provide a source of power to one or more of the imaging device IC 134 and the implement analyzing device IC 140, in some examples, one or more of the imaging device IC 134 and the implement analyzing device IC 140 may include a battery (not shown) for powering one or more the imaging device IC 134 and the implement analyzing device IC 140.

Referring to FIG. 26, the fluid overflow passage 152 may be formed proximate or substantially below the cartridge receiver 122 to permit excess fluid F_(O) to evacuate the implement analyzing device 100. In one embodiment, the fluid F_(O) evacuates the implement analyzing device 100 with the assistance of gravity. The excess fluid F_(O) may flow: (1) over the over the fluid overflow edge 68 (see, e.g., FIG. 1B) of each of the first fluid retainer cartridge assembly 10 ₁, the second fluid retainer cartridge assembly 10 ₂ and the third fluid retainer cartridge assembly 10 ₃, (2) out of the cartridge receiver 122 and then (3) out of the fluid overflow passage 152.

Referring to FIGS. 28-30, the implement analyzing device 100 may further include at least one cartridge heater 168. The at least one cartridge heater 168 may be disposed within or secured to a base portion 170 (see, e.g., FIGS. 25-26) of the body 124 of the cartridge receiver 122. The base portion 170 of the body 124 of the cartridge receiver 122 may be located opposite the at least one first opening 126 formed by the body 124 of the cartridge receiver 122.

The at least one cartridge heater 168 is defined by a body 172 having a base portion 172 a, a front portion 172 b and a rear portion 172 c. The body 172 may be an aluminum die cast cube containing heater tape with a thermistor embedded in thermal epoxy. Optionally, the aluminum die cast cube may also house a small vibration motor (not shown) that may impart vibrations to the exemplary fluid retainer cartridge assemblies 10 ₁, 10 ₂, 10 ₃ for mixing and agitating the fluid F contained by the exemplary fluid retainer cartridge assemblies 10 ₁, 10 ₂, 10 ₃.

Each of the base portion 172 a, the front portion 172 b and the rear portion 172 c is defined by a cartridge supporting surface 174 a, 174 b, 174 c. In an example, the cartridge supporting surface 174 a, 174 b of each of the base portion 172 a and the front portion 172 b may be defined by a substantially flat or planar surface. In another example, the cartridge supporting surface 174 c of the rear portion 172 c may include a substantially flat or planar surface that is interrupted by a curved or arcuate surface portion defined by a radius R_(172c) (see, e.g., FIG. 30).

The cartridge supporting surface 174 a, 174 b, 174 c of each of the base portion 172 a, the front portion 172 b and the rear portion 172 c defines a cartridge-receiving gap 176. As seen in FIG. 29, the cartridge-receiving gap 176 is partially defined by the cartridge supporting surface 174 b of the front portion 172 b extending away from the cartridge supporting surface 174 a of the base portion 172 a at a distance D_(172b). With further reference to FIG. 29, the cartridge-receiving gap 176 is further partially defined by the cartridge supporting surface 174 c of the rear portion 172 c extending away from the cartridge supporting surface 174 a of the base portion 172 a at a distance D_(172c). The distance D_(172b) may be greater than the distance D_(172c). Furthermore, as seen in FIG. 30, the cartridge-receiving gap 176 is further partially defined by the cartridge supporting surface 174 b of the front portion 172 b being spaced apart from the cartridge supporting surface 174 c of the rear portion 172 c at a distance D_(172a).

As seen in FIG. 31, the cartridge-receiving gap 176 defined by the cartridge supporting surface 174 a, 174 b, 174 c of each of the base portion 172 a, the front portion 172 b and the rear portion 172 c may be sized for receiving at least the cap portion 14 of the exemplary fluid retainer cartridge assemblies 10 ₁, 10 ₂, 10 ₃. In an example, the distance D_(172b) defining the cartridge supporting surface 174 b of the front portion 172 b may be sized for extending across at least the length L₅₆ (see, e.g., FIG. 8) of the implement proximal end retainer portion 56 of the tongue-receiving housing 54 of the cap portion 14. In an example, the distance D_(172c) defining the cartridge supporting surface 174 c of the rear portion 172 c may be sized for extending across at least a portion the length L₆₀ (see, e.g., FIG. 9) of at least the arcuate-shaped channel 60 of the body 52 of the cap portion 14. Furthermore, the radius R_(172c) defining the curved or arcuate surface portion of the cartridge supporting surface 174 c of the rear portion 172 c may be sized for receiving and corresponding to the radius R₆₀ (see, e.g., FIGS. 10, 13) or radial geometric component extending into the front surface 52 _(F) of the body 52 of the cap portion 14 that defines the arcuate-shaped channel 60.

Once the cap portion 14 is disposed within the cartridge-receiving gap 176 of the body 172 of the at least one cartridge heater 168, portions of the outer surface of the body 52 of the cap portion 14 may be disposed adjacent the cartridge supporting surface 174 a, 174 b, 174 c of each of the base portion 172 a, the front portion 172 b and the rear portion 172 c of the body 172 of the at least one cartridge heater 168 for thermally transferring heat from the at least one cartridge heater 168 to the body 52 of the cap portion 14 (and, ultimately, to the fluid F contained within the body 52 of the cap portion 14). In an example, the proximal end surface 52 _(P) of the body 52 of the cap portion 14 may be disposed adjacent or proximate the cartridge supporting surface 174 a of the base portion 172 a of the body 172 of the at least one cartridge heater 168. Further, in an example, the front surface 52 _(F) defined the by implement proximal end retainer portion 56 of the tongue-receiving housing 54 of the cap portion 14 may be disposed adjacent or proximate the cartridge supporting surface 174 b of the front portion 172 b of the body 172 of the at least one cartridge heater 168. Yet even further, in an example, the rear surface 52 _(R) defined by the body 52 of the cap portion 14 may be disposed adjacent or proximate the cartridge supporting surface 174 c of the rear portion 172 c of the body 172 of the at least one cartridge heater 168.

After the cap portion 14 is disposed within the cartridge-receiving gap 176 of the body 172 of the at least one cartridge heater 168 as described above and the body 52 of the cap portion 14 makes contact with the at least one cartridge heater 168 as described above, the corresponding contact there-between acts as thermal transfer regions, to thereby thermally couple a test strip assay I at the cap portion with the at least one cartridge heater 168. The rear and front surfaces 52 _(R) and 52 _(F) defined by the body 52 of the cap portion 14 preheats the fluid F before the fluid F flows through the fluid-flow passage 32 formed by the flange 28 of the base portion 12. Thereafter, the implement proximal end retainer portion 56 of the tongue-receiving housing 54 of the cap portion 14 heats the fluid F prior to and after the fluid F comes into contact with the test strip assays I₁, I₂, I₃. The ability to provide heat to both of the rear and front surfaces 52 _(R) and 52 _(F) of the body 52 of the cap portion 14 and to the implement proximal end retainer portion 56 of the tongue-receiving housing 54 of the cap portion 14 may ensure a more consistent testing temperature of the fluid F.

With reference to FIGS. 32-34 and as described above, the base portion 170 (that receives or houses the at least one cartridge heater 168) of the body 124 of the cartridge receiver 122 is located axially opposite the at least one first opening 126 formed by the body 124 of the cartridge receiver 122. Furthermore, as seen in FIGS. 31-32, the at least one cartridge heater 168 may include: a first cartridge heater 168 a; a second cartridge heater 168 b; and a third cartridge heater 168 c. In an example, the first cartridge heater 168 a corresponds to, is located opposite and axially aligned with the first cartridge receiving opening 126 a of the at least one first opening 126. In another example, the second cartridge heater 168 b corresponds to, is located opposite and axially aligned with the second cartridge receiving opening 126 b of the at least one first opening 126. In yet another example, the third cartridge heater 168 c corresponds to, is located opposite and axially aligned with the third cartridge receiving opening 126 c of the at least one first opening 126.

Referring to FIGS. 28-31 and 35, each of the first cartridge heater 168 a, the second cartridge heater 168 b and the third cartridge heater 168 c may be connected to the implement analyzing device IC 140 by one or more communication links 178. The one or more communication conduits 178 may permit the implement analyzing device IC 140 to selectively activate any of the first cartridge heater 168 a, the second cartridge heater 168 b and the third cartridge heater 168 c. Selective activation of any of the first cartridge heater 168 a, the second cartridge heater 168 b and the third cartridge heater 168 c may result from software/instructions stored in the memory hardware 145 and executed by the data processing hardware 143 of the implement analyzing device IC 140.

In an example, selective activation of any of the first cartridge heater 168 a, the second cartridge heater 168 b and the third cartridge heater 168 c may arise from different test types (e.g., specified by the test information 149) to be conducted on the first plurality of test strip assays I₁-I₃ contained by the first fluid retainer cartridge assembly 10 ₁, the second plurality of test strip assays I₁-I₃ contained by the second fluid retainer cartridge assembly 10 ₂ and the third plurality of test strip assays I₁-I₃ contained by the third fluid retainer cartridge assembly 10 ₃, which may each require different testing temperatures. For instance, the test information 149 associated with each test strip assay I₁-I₃ retained within one of the fluid retainer cartridge assemblies 10 ₁-10 ₃ may specify a desired temperature of the fluid (F) retained therein. Accordingly, each of the first cartridge heater 168 a, the second cartridge heater 168 b and the third cartridge heater 168 c that is associated with each of the first, second and third cartridge receiving openings 126 a, 126 b, 126 c may be controlled independently to carry out such non-similar temperature tests.

Referring back to FIGS. 28-30, the front portion 172 b and the rear portion 172 c of the body 172 are not connected by corresponding side portions. The lack of side portions reduces an amount of heat transfer between neighboring cartridge heaters 168 a-168 b and 168 b-168 c, and, thus, between neighboring fluid retainer cartridge assemblies 10 ₁, 10 ₂, 10 ₃ contained therein. By reducing heat transfer between neighboring fluid retainer cartridge assemblies 10 ₁, 10 ₂, 10 ₃, independent heating of each fluid retainer cartridge assembly 10 ₁, 10 ₂, 10 ₃ may be more accurately controlled. Accordingly, cartridge heaters 168 a-c may be selectively activated independently from one another such that each heating device 168 a-c is thermally coupled to a corresponding removably-inserted fluid retainer cartridge assembly 10 (e.g., assembly 10 ₁) and thermally isolated from the one or more other fluid retainer cartridge assemblies 10 (e.g., assemblies 10 ₂ and 10 ₃). Moreover, each heating device (e.g., each cartridge heater 168 a-c) may be selectively deactivated after a prescribed period of time specified by the test information 149. Here, the prescribed period of time may refer to the analysis duration during which the fluid (F) is in contact with the result region R on the one or more test strip assays I₁-I₃, or the prescribed period of time may refer to a time duration required to heat the fluid (F) to the desired temperature.

Activation of any of the first cartridge heater 168 a, the second cartridge heater 168 b and the third cartridge heater 168 c results in any of the first cartridge heater 168 a, the second cartridge heater 168 b and the third cartridge heater 168 c generating heat. The generated heat by any of the first cartridge heater 168 a, the second cartridge heater 168 b and the third cartridge heater 168 c may be directed to any portion (e.g., the cap portion 14) of the fluid retainer cartridge assembly 10 that is disposed within the cartridge-receiving gap 176 defined by the cartridge supporting surface 174 a, 174 b, 174 c of each of the base portion 172 a, the front portion 172 b and the rear portion 172 c of the body 172 of the at least one cartridge heater 168.

Referring to FIG. 35, the implement analyzing device 100 may also include a fan 180 that is located within the cavity 120. The fan 180 may be secured to one or more of the inner surface 114 of the support member 102 and the inner surface 118 of the housing 104. The fan 180 may include a motor (not shown) that is connected to the implement analyzing device IC 140 by a communication link 182. The motor associated with the fan 180 may be activated or deactivated upon the implement analyzing device IC 140 sending an activation or deactivation signal to the fan 180 by way of the communication link 182.

Activation of the fan 180 may occur in order to cool one or more components that are located within the cavity 120 of the implement analyzing device 100. The one or more components within the cavity 120 that may need to be cooled may include, but is not limited to one or more of the: the imaging device IC 134, the implement analyzing device IC 140 and the at least one cartridge heater 168. In some implementations, the fan 180 may be automatically activated if, for example, the implement analyzing device IC 140 determines (e.g., senses) that the at least one cartridge heater 168 exceeds a predetermined test temperature (i.e., the desired temperature specified by the test information 149) for the purpose of reducing or maintaining the at least one cartridge heater 168 at or a below the predetermined test temperature. Such a determination made by the implement analyzing device IC 140, may occur in response to a temperature and/or humidity sensor 181 positioned within the cavity 120 and communicatively-coupled to the implement analyzing device IC 140 by a communication link 183.

The implement analyzing device 100 may include other components not shown in the Figures. For example, the implement analyzing device 100 may also include a vibration motor that provides haptic feedback during a test or for agitating the fluid F within any fluid retainer cartridge assembly 10. In another example, the implement analyzing device 100 may also include an onboard three axis accelerometer for indicating to a user if the implement analyzing device 100 is not level in order to mitigate an adverse condition that may negatively impact fluid flow within any fluid retainer cartridge assembly 10. In yet another example, the implement analyzing device 100 may also include antennas or sensors for a variety of functions relating to global positioning systems (GPS), radio frequency identification (RFID) recognition, barometer readings and the like; such additional antennas or sensors may provide additional information about testing conditions that may be considered during analysis.

A method for utilizing the implement analyzing device 100 is now described. Firstly, as seen in FIG. 23, at least one fluid retainer cartridge assembly 10 ₁, 10 ₂, 10 ₃ of a plurality of fluid retainer cartridge assemblies 10 _(P) may be loaded with one or more of the test strip assays I₁, I₂, I₃. As seen in FIGS. 24A-24B, 25, 26, the at least one fluid retainer cartridge assembly 10 ₁, 10 ₂, 10 ₃ of the plurality of fluid retainer cartridge assemblies 10 _(P) that have been loaded with the test strip assays I₁, I₂, I₃ then may be interfaced with the implement analyzing device 100, e.g., by inserting the at least one fluid retainer cartridge assembly 10 ₁, 10 ₂, 10 ₃ of the plurality of fluid retainer cartridge assemblies 10 _(P) through the at least one first opening 126 (e.g., 126 a, 126 b, and 126 c) of the body 124 of the cartridge receiver 122. Alternatively, test strip assays I₁, I₂, I₃ may be loaded into the at least one fluid retainer cartridge assembly 10 ₁, 10 ₂, 10 ₃ of a plurality of fluid retainer cartridge assemblies 10 _(P) after the at least one fluid retainer cartridge assembly 10 ₁, 10 ₂, 10 ₃ of a plurality of fluid retainer cartridge assemblies 10 _(P) have been interfaced with the implement analyzing device 100. In one embodiment, as seen in FIG. 1B, each loaded at least one fluid retainer cartridge assembly 10 ₁, 10 ₂, 10 ₃ of a plurality of fluid retainer cartridge assemblies 10 _(P) may be dosed with an amount of fluid F while, if desired, each loaded at least one fluid retainer cartridge assembly 10 ₁, 10 ₂, 10 ₃ of a plurality of fluid retainer cartridge assemblies 10 _(P) is disposed within the implement analyzing device 100. Alternatively, the plurality of fluid retainer cartridge assemblies 10 _(P) may be dosed with an amount of fluid F before test strip assays I₁, I₂, I₃ are loaded into the at least one fluid retainer cartridge assembly 10 ₁, 10 ₂, 10 ₃ of a plurality of fluid retainer cartridge assemblies 10 _(P).

The implement analyzing device 100 may be actuated before, during or after dosing each loaded at least one fluid retainer cartridge assembly 10 ₁, 10 ₂, 10 ₃ of a plurality of fluid retainer cartridge assemblies 10 _(P) with the amount of fluid F such that the implement analyzing device 100 can monitor, read, and analyze the one or more of the test strip assays I₁, I₂, I₃ before, during, and after dosing. Actuation of the implement analyzing device 100 may include one or more of the imaging device 136 obtaining one or more images I (see, e.g., FIGS. 25-26) of the of the one or more of the test strip assays I₁, I₂, I₃ and may include activating the at least one cartridge heater 168.

In an example, as seen in FIGS. 25-26, the imaging device 136 of the imaging device IC 134 may continuously capture image data 141 of the one or more of the test strip assays I₁, I₂, I₃. The image data 141 captured by the imaging device 136 are communicated from the imaging device IC 134 to the implement analyzing device IC 140 by way of the communication link 142.

Referring back to FIG. 35, the data processing hardware 143 of the implement analyzing device IC 140 may execute a test strip assay recognition algorithm to detect one or more test strip assays I received by the cartridge receiver 122 based on the image data 141 received by the imaging device 136. For instance, the test strip assay recognition algorithm may determine when a test strip assay I₁, I₂, I₃ is arranged within the region R₁₂₉ of the at least one second opening 128 formed by the body 124 of the cartridge receiver 122 for the purpose of executing an analysis routine on each detected corresponding test strip assay I₁, I₂, I₃ based on the corresponding test information 149. In one embodiment, the test strip assay recognition algorithm may continuously determine whether a test strip assay I₁, I₂, I₃ is arranged within the region R₁₂₈ of the at least one second opening 128 formed by the body 124 of the cartridge receiver 122 for the purpose of executing an analysis routine on each detected corresponding test strip assay I₁, I₂, I₃.

In some scenarios, the test strip assay recognition algorithm analyzes multiple cartridge assemblies 10 ₁, 10 ₂, 10 ₃ through corresponding second openings 128 a, 128 b, 128 c independently from one another to detect whether one or more test strip assays I are arranged in each independent cartridge assembly 10 ₁, 10 ₂, 10 ₃. For instance, the data processing hardware 143 may select any cartridge assembly 10 ₁, 10 ₂, 10 ₃ and use the image data 141 to detect whether one or more test strip assays I are arranged within the selected port/cartridge assembly 10 ₁, 10 ₂, 10 ₃ independently from the other cartridge assemblies 10 ₁, 10 ₂, 10 ₃. Thus, the imaging device 136 may capture image data 141 directed toward the region R₁₂₉ of the at least one second opening 128 formed by the body 124 of the cartridge receiver 122 and the data processing hardware 143 of the implement analyzing device IC 140 may use the image data 141 to individually monitor each cartridge assembly 10 ₁, 10 ₂, 10 ₃ for the presence of one or more test strip assays I arranged therein. Accordingly, each cartridge assembly 10 that has been inserted into the cartridge receiver 122 may be monitored separately for the presence of test strip assays I, or two or more cartridge assemblies 10 may be monitored simultaneously for the presence of test strip assays I. Similarly, each cartridge assembly 10 that has been inserted into the cartridge receiver 122 may be independently heated and/or the capture image data 141 independently analyzed (for the test strip assays I₁, I₂, I₃ in that cartridge assembly 10) separate from any other cartridge assembly 10; or two or more cartridge assemblies 10 may be simultaneously heated and/or the capture image data 141 simultaneously analyzed (for the test strip assays I₁, I₂, I₃ in those cartridge assemblies 10). Furthermore, the test strip assay recognition algorithm may analyze the image data 141 received from the imaging device 136 to identify one or more indicia markings disposed on each detected test strip assay I₁, I₂, I₃. The indicia markings may include at least one of the barcode data B, the alphanumerical data #, or the color data (see, FIG. 1A). Thereafter, the data processing hardware 143 may determine the unique test strip identifier 147 associated with each detected test strip assay I₁, I₂, I₃ based on the identified indicia markings, and retrieve the test information 149 associated with each detected test strip assay I₁, I₂, I₃ using the corresponding unique test strip identifier 147. Here, the memory hardware 145 contains a database/data store linking unique test strip identifiers 147 with corresponding test information 149. Manufacturers of the test strip assays may provide the test strip information 149. The memory hardware 145 may be internal (e.g., associated with the implement analyzing device IC 140) or externally connected as one of the data input/output devices 162. Additionally or alternatively, the optical scanner 158 may scan the barcode data B and provide the scanned barcode data B to the data processing hardware 143 for determining the unique test strip identifier 147. Here, the unique test strip identifier 147 may be obtained for test strip assays I₁, I₂, I₃ prior to being inserted into the implement analyzing device 100.

With continued reference to FIG. 35, the data processing hardware 143 may execute, for each detected test strip assay I₁, I₂, I₃, the analysis routine on the corresponding test strip assay I after being contacted with the fluid F based on the corresponding test information 149. The analysis routine is configured to analyze the detectable signal DS (e.g., a color change or intensity information) within the result region R located on the corresponding test strip assay I based on the image data 141, and determine the test result 190 indicating the presence and/or concentration of the chemical analyte within the fluid F. Each test result 190 may be tagged with the corresponding unique test strip identifier 147 and stored in the memory hardware 145. In some examples, the data processing hardware 143 displays the test result 190 for each detected test strip assay I on the graphical user interface 153 executing on the touchscreen 154.

In some implementations, the data processing hardware 143 automatically executes an analysis routine on a corresponding detected test strip assay I in response to obtaining the test information 149 associated therewith. In other implementations, after obtaining the test information 149, the data processing hardware 143 analyzes the image data 141 received from the imaging device 136 to measure a level of the fluid (F) retained by the corresponding removably-inserted fluid retainer cartridge assembly 10, and determines whether the measured level of the fluid F is at least a threshold fluid level. The test information 149 may specify the threshold fluid level, whereby the threshold fluid level is a volume of fluid F sufficient for contacting the results region R on each detected test strip assay I retained by the corresponding fluid retainer cartridge assembly 10 to initiate the chemical reaction (if any) with a chemical analyte. Thereafter, the data processing hardware 143 may execute the analysis routine on each detected test strip assay I retained by the corresponding fluid retainer cartridge assembly 10 in response to determining the measured level of the fluid is at least the threshold fluid level. In some examples, the data processing hardware 143 initiates a timer responsive to the measured level of the fluid F being at least the threshold fluid level. In these examples, the analysis routine determines the test result 190 associated with each detected test strip assay I retained by the corresponding fluid retainer cartridge assembly 10 when the timer satisfies the analysis duration specified by the test information 149. In some configurations, the cap portion 14 of the fluid retainer cartridge assembly 10 is translucent so that the fluid F is visible through the second opening 126 of the cartridge 122 and, thus, measurable from the image data 141 captured by the imaging device 136.

Similar to how the test strip assay recognition algorithm analyzes multiple cartridge assemblies 10 ₁, 10 ₂, 10 ₃ independently from one another for detecting the presence of test strip assays I, the data processing hardware 143 may execute the analysis routine on each detected test strip assay I retained by a corresponding selected fluid retainer cartridge assembly 10 independently from other detected test strip assays I retained by other corresponding fluid retainer cartridge assemblies 10. Thus, while cartridge assemblies 10 ₁, 10 ₂, 10 ₃ may each retain at least one test strip assay I detected by the recognition algorithm, the analysis routine may analyze the at least one test strip assay I retained by the cartridge assembly 10 ₂ independently from the at least one test strip assay I retained by the other cartridge assembly 10 ₁, 10 ₃. For instance, the analysis routine may analyze assays I within cartridge assembly 10 ₂ while waiting for the measured fluid level of the fluid within at least one of the other cartridge assemblies 10 ₁, 10 ₃ to reach the threshold fluid level. In another scenario, the analysis routine may analyze assays I retained within cartridge assembly 10 ₂ the recognition algorithm is continuously monitoring the other cartridge assemblies 10 ₁, 10 ₃ for the presence of test strip assays I. In some implementations, the analysis routine analyzes test strip assays I retained by at least two different cartridge assemblies 10 simultaneously.

In an example, activation of the at least one cartridge heater 168 during, for example, a period of time results in the at least one cartridge heater 168 imparting heat to at least, for example, the cap portion 14 of the fluid retainer cartridge assembly 10, which may also contain the fluid F. The imparted heat serves to incubate at least, for example, the cap portion 14 of the fluid retainer cartridge assembly 10 if a particular test requires the fluid F contained therein to be heated to a desired temperature specified by the test information 149.

In some implementations, the color and/or intensity information associated with the detectable signal DS includes line intensity of one or more result lines (e.g. control lines) superimposed in the result region R of the corresponding test strip assay I₁, I₂, I₃. The line intensity of the one or more result lines is analyzed by the analysis routine. In some examples, to expedite the analysis routine, the analysis routine may be further configured to determine a rate of change in the line intensity of the one or more result lines, and predict the test result 190 indicating the presence and/or concentration of the chemical analyte before result lines are fully developed, i.e., before the end of the analysis duration.

Before or after the image data 141 is ready to be analyzed, the data processing hardware 143 (i.e., processor) of the implement analyzing device IC 140 may also execute a series of result line centering routines each used to ensure that the region of interest (i.e. result region R) for each test and result line is centered. Line centering information specified by the testing information 149 associated with each test strip assay I₁, I₂, I₃ may vary by the lot in which each test strip assay I₁, I₂, I₃ was manufactured. In some instances, the series of line centering algorithms may auto-detect and position the center using the line centering information, even with the inherent positional variation. The line intensity of each line on each test strip assay I₁, I₂, I₃ is read and the quantified results are calculated, displayed and saved in the memory hardware 145. Accordingly, execution of the analysis routine may include execution of the result line centering routine on the corresponding test strip assay (I) to center one or more result lines superimposed in the result region R. Here, the result line centering routine is configured to identify the one or more result lines superimposed in the result region R based on the image data 141 received from the imaging device 136, and adjust a position of the one or more result lines to align with result line centering information specified by the test information 149.

Referring to FIG. 36, the implement analyzing device 100 may further include a plurality of light sources 184 arranged within the cavity 120 and directed toward the region R₁₂₉ of the at least one second opening 128 formed by the body 124 of the cartridge receiver 122 for the purpose of illuminating regions of each test strip assay I₁, I₂, I₃ that is to be imaged by the imaging device 136 as described above.

In an example, the plurality of light sources 184 are secured to the imaging device IC 134. In an implementation, the plurality of light sources 184 include light emitting diode (LED) light sources. In some instances, the plurality of light sources 184 include eight LED light sources. The plurality of LED light sources may emit any desired type of color light (that is defined, e.g., by wavelength) including but not limited to: visible light; white light; colored light; and infrared light.

In an example, the imaging device IC 134 may include two sets of four LED light sources 184. In an example, the imaging device IC 134 may independently operate each LED light source 184 of the two sets of four LED light sources 184. Furthermore, in an example, the imaging device IC 134 may include two independent lighting circuits that allow for different illumination conditions within the cavity 120 that may increase the potential of test types that may be conducted by the implement analyzing device 100.

The method may also include one or more calibration steps for ensuring that the inter-unit variability is low. Many of the calibration steps may be performed a single time before the implement analyzing device 100 is utilized for a first time. Calibration may occur at the manufacturer or by a user in the field.

In an example, illumination calibration may set an illumination percentage of all the plurality of light sources 184 associated with the imaging device IC 134. A target brightness may be determined through testing and the goal of the illumination calibration routine is to match actual brightness to a target brightness. Referring to FIGS. 37-38, illumination calibration may be conducted by inserting a calibration cartridge 10 c into a central port (e.g., the second cartridge receiving opening 126 b) of the at least one first opening 126 formed by the body 124 of the cartridge receiver 122. The imaging device 136 may obtain an image of the calibration cartridge 10 c, which is subsequently provided to the implement analyzing device IC 140 for conducting the calibration process. An average brightness value is determined for the region of interest of the calibration cartridge 10 c with all settings of the imaging device 136 set to default values. The illumination value is then adjusted so that the average brightness value is within a set tolerance of the target brightness value.

In another example, white balance calibration may be used for setting one or more color balance settings on the imaging device IC 134; calibrating these values reduces a color variance between different implement analyzing devices 100 due to any inherent differences of the imaging devices 136 and plurality of light sources 184 installed therein. The same calibrator cartridge 10 c and region of interest described above may be used for achieving white balance calibration as was used for brightness calibration. The imaging device 136 may obtain an image of the calibration cartridge 10 c, which is subsequently provided to the implement analyzing device IC 140 for conducting the calibration process. In some instances, the red balance value and the blue balance value are determined through an iterative process aimed at reducing the chrominance values to zero.

In yet another example, a lens calibration routine (for calibrating a lens associated with/attached to the imaging device 136) may be used for post-processing correction of a vignetting effect that is inherent in the imaging device/lens setup. The lens calibration routine (that is conducted in response to the imaging device 136 obtaining an image of the calibration cartridge 10 c, which is subsequently provided to the implement analyzing device IC 140 for conducting the calibration process) may determine the intensity throughout the calibrator cartridge 10 c and fits a curve to the white region; this curve can then be used to correct the image, reducing the color variance between ports within the implement analyzing device 100.

In another example, port calibration may be used for locating each of the first, second and third cartridge receiving openings 126 a, 126 b, 126 c to make the identification of each test strip assay I₁, I₂, I₃ easier and more accurate. The first, second and third cartridge receiving openings 126 a, 126 b, 126 c are found by inserting a calibrator cartridge 10 c into each of the first, second and third cartridge receiving openings 126 a, 126 b, 126 c. The imaging device 136 may obtain an image of the calibration cartridge 10 c, which is subsequently provided to the implement analyzing device IC 140 for conducting the calibration process. The black regions of the calibrator cartridge 10 c are used as fiducial markers, allowing for accurate determination of the cartridge boundaries. Techniques such as edge detection may additionally or alternatively be used to locate the boundary of each port within the captured image data 141.

The data processing hardware 143 of the implement analyzing device IC 140 may execute a test strip assay recognition algorithm to detect one or more test strip assays I received by the cartridge receiver 122 based on the image data 141 received by the imaging device 136. A third test strip assay I₃ may be detected and includes a location within the first fluid retainer cartridge assembly 10 ₁, while first, second, and third test strip assays I₁, I₂, I₃ may be detected and include locations within the second fluid retainer cartridge assembly 10 ₂. Both the port calibration and test strip recognition algorithm may use a dynamic threshold to more accurately identify the bounds. When a strip is found, its specific position within in the cartridge receiver 122 can be saved for testing purposes. The data processing hardware 143 may execute the recognition algorithm to continuously look for the presence of test strips to automatically trigger the analysis. This feature can also be used to monitor the test and ensure the strip has not been removed during analysis.

In yet another example, crosshair calibration is an additional positional calibration of the internal components of the implement analyzing device 100. In an example, a t-shaped crosshair T (see, e.g., FIG. 38) of the calibrator cartridge 10 c allows for both X and Y positional calibration offsets to be generated; the offsets are determined as the distance, both in X and in Y, from the expected location. The imaging device 136 may obtain an image of the calibration cartridge 10 c, which is subsequently provided to the implement analyzing device IC 140 for conducting the calibration process. Using the offsets, the implement analyzing device 100 can more accurately locate specific characteristics on the cartridges or inserted test strip assays I₁, I₂, I₃.

In another example, a cartridge track may include white circular markers on either side that are imaged by the imaging device 136, which is subsequently provided to the implement analyzing device IC 140 for conducting the calibration process for validating both position of internal components as well as illumination. The position and illumination values of these spots are saved during the overall calibration routine. These values are then checked every time the implement analyzing device 100 is turned on. If the position or illumination of the regions of interest are outside of the set threshold, the validation will not pass. This can indicate to the user that there is an issue with the implement analyzing device 100 that could cause invalid results. If the illumination values are not within tolerance for the predetermined regions of interest, this could indicate that the alignment of the internal components has been compromised or that the plurality of light sources 184 associated with the imaging device IC 134 are not functioning how they did during calibration.

FIG. 39 is a flow chart of an example method 4200 for determining a test result 190 indicating a presence and/or concentration of a chemical analyte within a fluid F in contact with a test strip assay I.
